Barrel Roller Trophy
Fly through 500 Rings in Campaign mode.
Rings are another objective scattered about various levels. They simply appear as a Gold Ring which you have to fly through. Despite what the trophy description states, these rings can be flown through outside of Campaign Mode i.e. in Quick Flap Mode and will still count towards the trophy. Flying through most of the rings in the single-player campaign should net you around 250 rings leaving the other 250 free for you to scavenge in the Quick Flap mode: 'Rings Challenge'. I recommend replaying the third event over and over in order to earn this trophy as fast as possible. All rings earned are cumulative across Campaign and Quick Flap.
